Abstract

An apparatus for eliciting a blood sample is presented having a lancet for lancing a body part of a user and a cleaning member of absorbent material operable to clean a surface of the body part, the apparatus being configured such that in use the lancet is moved to lance a body part of a user and subsequently the cleaning member is moved to contact the body part of the user so as to remove blood from the surface of the body part prior to collection of the blood sample from the surface of the body part.

Claims

1. A lancing device, comprising:

a curved outwardly facing edge;

a lancet positioned adjacent to the outwardly facing edge, wherein the lancet is configured to change from a pre-operational shape to an operational shape, and wherein the lancet is comprised of a resilient material such that the lancet is bent when in the pre-operational shape and straight when in the operational shape;

a cleaning swab positioned adjacent to the outwardly facing edge at a radial distance away from the lancet; and

a lancet housing located adjacent to the outwardly facing edge of the lancing device, wherein the lancet and the cleaning swab are disposed within the lancet housing, wherein the lancet housing comprises a removable seal that holds the lancet in the pre-operational shape, covers the cleaning swab, and maintains sterility of the lancet, and wherein the removable seal is secured to the outwardly facing edge of the lancet housing by a heat seal connection or an adhesive.

2. The lancing device of claim 1, wherein the lancet further comprises a flexible portion and a rigid portion.

3. The lancing device of claim 1, wherein the removable seal covers the lancet.

4. The lancing device of claim 1, wherein the cleaning swab contains an antiseptic solution.

5. The lancing device of claim 4, wherein the antiseptic solution comprises an alcohol.

6. The lancing device of claim 1, wherein the lancet housing further comprises a recess, and wherein the cleaning swab is positioned in the recess.

8. The lancing device of claim 1, further comprising a blood collection part and an analyte measuring part.

7. A lancing device comprising:

a curved outwardly facing edge;

a lancet positioned adjacent to the outwardly facing edge, wherein the lancet is configured to change from a pre-operational shape to an operational shape, and wherein the lancet is comprised of a resilient material such that the lancet is bent when in the pre-operational shape and straight when in the operational shape;

a cleaning swab positioned adjacent to the outwardly facing edge at a radial distance away from the lancet; and

a lancet housing located adjacent to the outwardly facing edge of the lancing device, wherein the lancet and the cleaning swab are disposed within the lancet housing, wherein the lancet housing comprises a removable seal that holds the lancet in the pre-operational shape, covers the cleaning swab, and maintains sterility of the lancet, and wherein the removable seal exerts a bending force on the lancet to maintain the lancet in the pre-operational shape.

9. The lancing device of claim 7, wherein the lancet further comprises a flexible portion and a rigid portion.

10. The lancing device of claim 7, wherein the removable seal covers the lancet.

11. The lancing device of claim 7, wherein the cleaning swab contains an antiseptic solution.

12. The lancing device of claim 11, wherein the antiseptic solution comprises an alcohol.

13. The lancing device of claim 7, wherein the lancet housing further comprises a recess, and wherein the cleaning swab is positioned in the recess.

14. The lancing device of claim 7, further comprising a blood collection part and an analyte measuring part.
